1- At the outset, we should learn how to promptly submit to the command of Allah without showing any objection. When the Companions of the Prophet received imperative to direct their faces to the kaʿbah, they have immediately responded to the divine command.
Abdullah bin Umar (may Allah be pleased with him) reported that while the people were performing the ṣubḥ prayer at Qubā’, someone came to them and said “Last night some Quran was revealed to the Prophet (peace be upon him) and he was commanded to face the kaʿbah so face it.” They had been facing al-Shām (the Levant) and so they turned towards the kaʿbah.”
2- Changing the qibla is a proof on the occurrence of abrogation in Islamic Shariah. Abrogation is the annulment of a legal ruling by a subsequent or later ruling. Allah abrogated the ruling of directing one’s face to Jerusalem during prayer to the Kaʿbah.
3- Changing the qiblah refers to the great status of the Prophet Mohammad (peace be upon him). Allah responded to his internal wish to face the Kaʿbah.
4- Finally, the occasion of changing qibla refers to the fact that the Kaʿbah is the best place since Allah has chosen it to be the place where all Muslims direct their faces in prayer.
Almighty Allah knows best.
